3. A method named getResult that takes three characters: the first two must contain numbers (1-9), the third must contain one of the five operations: +, -, *, /, %. The method returns a String that includes the two numbers, the operation, and the result. It must make sure that the first two characters are numbers by invoking the isANumber method, and that the third character is one of the valid operations by invoking the isAnOperation method. If not, it must return the statement "Invalid Input!". For example, if the first two characters contain the numbers 3' and 4', and the operation + is passed to the method it must return the following String: 3+4=7
